this is in no way a common thing.. get an oil pressure gauge..

 

Listen, this noise is in NO WAY a noise that can be cured with gauges, fluids, or anything of the sort. The noise i'm hearing after 2k RPM sounds like a hammer banging on the inside of a safe. It's FOR SURE metal clanking on metal and i just wanted to know if anyone else has had this problem. Now that i've been asking around, this site and others, I'm not the only one with this problem.

 

If your positive that the knock is at a constant rate and does not change w/t rpm then you wouldn't think it would be engine internals, would you?


Let us know what the dealer thinks, mabee your front diff might have something loose

 

I have no idea what it could be? The car doesn't shake, sputter, back fire, smoke,.... I have no warning lights on, never put anything less than 92 oct, wasn't driving hard, totaly stock, etc.. I was reading a thread that suggested that someone should unplug the battery and reset the ECU. Anyone disagree with that? I figure it's worth a try.

 

Rod knock is a known issue and as previously stated should be covered under warranty. Especially due to the fact taht this is happening that audibly at 2k rpm theres no way this is a fuel/tuning related issue. Definitely schedule an appointment to get it checked out at the dealership. Beforehand check the oil level for sure as oil starvation could be the causation. (may be the out for them to void your warranty so check it beforehand) Either way, you're stock and under warranty and to be sure you don't damage anything further I'd bring it in and get this on record and checked out. Good luck.

 

this scares me

 

These issues are somewhat isolated, and unfortunate for people who encounter them but not a general cause for concern. Mitsu even recognizes this through somewhat trouble free resolutions for claims related to rod knock, unless careless oil starvation is blatantly obvious.

Im at 31k miles and luckily I never encountered this, my engine has also never burnt a drop of oil either though. Its luck of the draw to an extent but these cars are pretty much tanks.

 

This could very well be a bad balancer shaft,or upper rod bearing ,meaning that the upper bearin flattened out ,wich can cause a sound of knock only on the down stroke cauing the noise to sound like it levels off with engine speed.Also go by a dealer and get a mitsu oil filter and put it on before you take it for service mitsu's b'youch asses will try the fram, purilator oil filters caused the engine to starve of oil and that voids your waranty sir , crap!

 

I'm not sure about what you're trying to say with that last comment? Get a new mitsu oil filter because why? I believe the one i have on now came from a mitsu dealer? Although i did buy this car from a personal seller who has been MORE than helpfull to me. He's on this forum alot and even made a post in this thread. VW4life. Either way, i'll check into it.

Oh also, i don't have a Mitsu dealer with in 200 miles of me, so i was hoping to get the work done at my local chrysler center.

 

There is no way that a company can deny warranty coverage for the brand of oil filter used.

A lot of people tend to forget that under the Magnusson-Moss Act a company has to prove that a part on your car actually CAUSED the failure. Mitsubishi is not going to do a thorough research of Fram Oil Filters just in order to deny your warranty claim.

Now, if your car is modified with a turbo back exhaust, or an ecu tune or something, they CAN and probably WILL put up an argument to grant you warranty coverage.

I have heard A LOT of stories of people with stock Evos having to fight with Mitsubishi to cover things like faulty AWD systems, clutch failures, and other issues, and more than likely it is because of their financial status. I have heard that they are pretty much doing everything they possibly can to cover ANY type of warranty repairs.

Don't let them take advantage of you. Fight them until you get your way.

 

It could be a number of things...axle/wheel bearing/rod knock/diff-tranny...my guess it sounds like an axle. You said it happens from 2k onwards and only happens on accelerate so it has to do with the driveline IMO.

 

You guys have all been very helpful. Thank you so much for all your advise. Last night i decided i'd try to disconect the battery to try and reset the ECU. On top of that, i changed my oil and filter (used a FRAM filter) to a heavier weight since i'm North Dakota where we're expecting a foot of snow tonight. Nothing... Same problem. This wouldn't be such a big deal to me ( I have a back up car to drive) if i had access to the warrant RIGHT NOW. I'm still waiting for the title to be put in my name since i bought it off a personal seller just a few weeks ago. As far as i know, it'll be complete this week. If my Chrysler dealer can't warranty it, i hope the Mitsu company will pay to have it shipped to Fargo 4 hours away

 

So far you have said that the noise:

• can be heard at any RPM greater than 2000
• does not change with wheel speed
• does not get louder or 'faster' with engine speed
• only happens under acceleration
• sounds like a metal on metal banging
• does not seem to affect the engine's performance
• does not throw any check engine lights (CEL)

Does the noise happen if you are parked and rev the engine?
Does the noise happen if you take any sudden or sharp turns?
Can you FEEL the banging through the pedals, steering wheel, or otherwise?
Does the noise happen more frequently if the weather is colder, hotter, or raining?
Does the noise happen more or less frequently if the engine is warmed up or cold?

More information could be helpful. At the very least, you should call the Mitsu dealership you would send the Evo to, and speak with the service manager. It will be very helpful if you are able to simply and accurately describe the problem, when it happens, and when it does not happen. Write all of this down then call and be sure to go through the list.


From what you've said, I could imagine that the exhaust slipped off of one of the hangers. I have had the same exact symptoms above on a different car (not Evo), and the exhaust was the issue. The banging seemed to be coming from the front, and could be felt through the tranny tunnel.

Hope this helps.

 

I realize the dealer is far away and you live in BFE, but really, this issue needs to be taken to a dealer, and I'd query the previous owner, why did he/she sell an 05 with 10k miles so soon?? Did THEY have the knock and decide to pawn it off?? See if the warranty has been transferred, should be, and take it to Mitsu, and DEMAND they give you a rental so you won't be without a ride. . .sorry man, really does sound like a rod knock, I've heard them, and it REALLY does sound like it. . .

 

The previous owner and i have been talking and emailing ALOT. I drove down to Virgina a few weeks ago to pick it up because he just bought a new RS and wanted to build a "sleeper". Since then, i've added another 2k+ miles and had NO problems what so ever. The problem i have now JUST happend this weekend. Saturday night to be exact. And yes, the car does make this noice when i rev it while it's parked. I didn't even think to post that fact? Does this change what the problem could be? Also, after i changed the oil and reset the ECU, i drove it around the block. Still made the noise, but there is NO problems with the way it drives. When i first heard the banging around this weekend, i was doing a quick pull to about 5k like i said. And just like the first day i drove it, she pulls strong and HARD. Would "rod knock" still allow me drive it with out any other symptoms other than some noise?

Evo Time- You asked alot of good questions and here are your answers. Again, thank you so much for taking the time to help me.
1- yes
2- only if accelerating, other wise, no.
3- can't feel anything. From inside the car with the windows up, i can hardly hear it in the 1st place.
4- Doesn't matter what temp it is outside. I did notice that when i first start it, sometimes, the clanking around will happen until the engine settles down. Maybe your exhaust theory?
5- Doesn't matter if the engine is cold or hot, the noise will happen on revs around 2k and higher.
